Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed. March 15, 1913. Serial No. 754,546.

To all whom it may concern:

Be it known that 1, Limits E. CHINNOGK, a citizen of the United States, and a resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented anew and useful Improvement in Car Transferring and Dumping Mechanism, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention relates in general to car handling mechanism, the principal adaptation herein shown and described being a mechanism for transferring and dumping mine cars, such as are employed in coal mines and the like; it is not meant, however, to imply a limitation of the invention to such held of use alone. The present mechanism as illustrated, moreover, is still more particularly designed for use in conjunction with superposed tipple tracks arranged as in Patent No. 1,017,868, to F. C. Greene e25 aZ., dated February 20, 1912.

The object of the present improvements is to provide a simple and inexpensively op erated type of construction whereby a loaded car may be received from one track, dumped, and transferred to another track either above or below such first track.

To the accomplishment of this and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but several of the various mechanical forms in which the principle of the invention may be used.

In said annexed drawings :Figure 1 is a plan view of two dumping and transfer-- ring machines embodying the present 1mprovements and placed side by side, the two machines being shown in two different operative positions, respectively; Fig. 2 is a side elevational view of one such machine showing the same in its normal position in which it is adapted to receive a loaded car from the lower of the two superposed tracks; Fig. 3 corresponds with Fig. 2, but shows the machine in an intermediate operative position wherein the car is tilted for dumping; Fig. 4 similarly illustrates the machine in yet another operative position in which the car, after bein dumped, is transferred to the upper of the superposed tracks; Fig. 5 is a rear elevational view of the dumping and transferring mechanism proper, showmg the parts in the same position as in Fig. 4; Fig. 6 is a side elevational view of a modified construction of operating mechanism for the machine; Figs. 7 and 8 similarly illustrate two other forms of operating mechanism, respectively; Fig. 9 is a plan view of an improved stop device designed for use with the foregoing car dumping and transferring mechanism; and Figs. 10 and 11 are cross-sectional views of such mechanism on the lines 10-10 and 11-11, respectively, Fig. 9.

It will be understood that while two of my improved machines are shown side by side in Fig. 1, there is no essential interrelation between the same such as makes their use in pairs essential; for in the present description only a single machine will be described, the two being thus illustrated in Fig. 1 merely to show conveniently such machine in two operative positions. Of course, the location of two or even more machines thus side by side is not infrequent in practice.

Referring to said Fig. l and to Figs. 2, 3 and 4:, it should be explained that the lowermost l of the two superposed tracks is intended to register with the. lower of the two tracks on a double deck cage (not shown) of the kind illustrated, for example, in the above-named Patent No. 1,017,868; and at the same time the upper track 2 of said figures will register with the upper track of said cage, the arrangement being such that a car may be simultaneously received from the lower deck of the cage and discharged on the latters upper deck. Suitable stop mechanism, comprising horns oscillatorily mounted and arranged to be con trolled by the movement of the dumping and car-transferring mechanism presently to be described, is provided to check the movement of the cars received on track 1 from the lower deck of the cage, and to permit such cars to pass onto the floating track-section 4, which constitutes the principle element of the dumping and transferring mechanism, only when such traclrsection is properly disposed to receive the same. This tracksection a just referred to is likewise provided with horns, or upwardly projecting arms f"), which act as stops for the car when it 1s receivedon said track section, said arms being longitudinally slidable on the forward end of the track section and backed by springs 6 to take up the shock, or jar, of the car.

It will be understood that the movement of the car, both off the lower deck of the cage and along the track 1 is designed to be by gravity, the track being suitably inclined with this in view. Similarly, the track 2, as well as the upper deck of the cage will be oppositely inclined so as to cause the cars to run by gravity in the proper d1rect1on to return from the dumping station to such cage.

The forward end of the tilting tracksection 4, is movably held between guideways 7, that incline upwardly and rearwardly at an angle of approximately 455 degrees, such guideways being conveniently formed by attaching angle bars to fiat plates extending from the lower to the upper track level. The track-section is thus movably held by being provided near its forward end with a transverse shaft or axle S on the outer ends of which are mounted wheels or rollers 9, which run in said guideways respectively. Near its rear end the track-section is provided with another transverse shaft 10, to which is attached an oscillatory arm or lever member 11 mounted upon a shaft 12 disposed to the rear of the guideways and on the level or a little below the level of the lower tracksection, such shaft 12 constituting a fixed axis about which the arm may swing. The length of this arm is substantially equal to the vertical distance between the two superposed tracks, and its axis of oscillation is so located that when said arm is swung into,

vertical position the axle carrying the wheels or rollers will be brought to the upper end of the inclined guideways (see Fig. 4) and substantially in horizontal alinement with the upper track. The effect of such oscillation of the arm 11 will be readily understood from a comparison of Figs. 2, 3 and 4, from which it will be observed that the first result is to swing the free end of the tilting tracksection a into a position wherein said section is substantially parallel with the inclined guideways 7, as shown in Fig. 3. In this position of the section the car may be readily dumped of its contents by simply opening its end-gate, this being done manually or by automatic means as desired. As the arm is swung into its extreme vertical position, that of Fig. 4, the car is restored to a horizontal position, on a level with the upper track, so that it may be readily discharged onto the latter and thence on the upper deck of the waiting cage. Suitable stop mechanism will be provided, of course, on the upper track to control the movement of the empty cars therealong and to hold the same until the cage is properly placed for receiving them.

As a matter of fact the track-section 4 in its lower position, as well as in its upper position is not quite horizontally disposed but is inclined to correspond with the adjacent track; especially with the upper track, since such inclination is utilized to discharge the car.

The means for operating the oscillatory arm may assume various forms. As shown in Figs. 1 to 5 inclusive, said means comprise a segmental gear 13 on the same shaft 12 that carries the arm 11, and a vertically reciprocable rack 14, which meshes with said gear. This rack is, in turn, operated by a power piston forming the central of three pistons disposed side by side beneath the lower track and operating in three corresponding cylinders. Steam or compressed air may be utilized in connection with the central cylinder 15 for positively operating the piston therein to elevate the rack. The

two outer cylinders (16) with their pistons a constituting a retarding device to control the movement and to regulate the speed of the power piston. To this end a bifurcated by-pass (17) provided with a suitable check valve (18) is connected with the opposite ends of these two outer cylinders, the latter being filled with dead oil or equivalent liquid, and the valve being arranged to permit such liquid to flow at a pre-determined rate when the rack is being operated in either upward or downward direction. The piston-rods 19 and 20, corresponding with the pistons in cylinders 15 and 16, arejoined to the rack by means of a common crosshead 21, Fig. in the modified construction of operating mechanism illustrated in Fig. 6, a segmental gear 22, similar to gear 13, is employed, but is operated by means of a pinion 23 instead of a rack. This pinion is arranged to be driven in a direction to raise the oscillatory arm and track-section by means of a power cylinder 24 connected with said pinion by a cable 25 and winding drum 26 geared thereto. It will be observed that the cable 25 passes around a sheave 27 carried on the piston rod 28 that is reciprocable in the cylinder 2%; also around a sheave 29 fixedly mounted beyond said cylinder 2% and piston rod 28, the opposite ends of said cable being attached fixed points, as 30. Reciprocation of the piston-rod will accordingly rotate the drum 26 in one direction or the other. The reverse movement of the pistonrod is checked by a piston on its opposite end that operates in a second cylinder 31 provided. with a by-pass 32 that regulates the flow of fluid from one end to the other, much as in the construction already described.

Fig. 7 illustrates the direct application of drivin means to the oscillatory arm 11, an electric motor 33 being connected to rotate a gear 34 through suitable driving mechanism including a worm, and said gear having a crank pin 35 connected by means of a rod 36 with a downward extension 37 of the oscillatory arm. By reversely connecting the motor with the driving mechanism, the arm may obviously be swung in either direction,

as desired. In Fig. 8 is illustrated yet another diect-connected form of driving mechanism, the arm 11 here being provided vith a segmental gear 22 as in the second described construction, that of Fig. 6, and a motor 38 being arranged to swing such gear, and thus the arm, through a suitable train of gears 39, as need not be further explained.

lVhatever the form of operating mecha nism for swinging the oscillatory arm, it will be observed that the latter, in combi nation with the unique arrangement of the tilting track-section, provides an extremely simple and yet eiiicient car dumping and transferring mechanism, the latter operation being effected simultaneously with the dumping. The amount of structural work required to support the mechanism is reduced to a minimum, and by reason of this fact and the simplicity observed throughout, there is very little to get out of order, this being a desirable result in mechanism of the class in hand, which is to be placed in charge of unskilled operators and subjected to hard usage. The amount of power required to operate the mechanism is not great, since the initial movei'nent of the swinging arm and trachsection into, for example, the position of Fig. 3, amounts simply to tilting the car and it is thereby discharged of its contents before it requires to be actually lifted onto the upper track level.

The construction of the stop or check mechani m for regulating the movement of the cars along the lower track from the o the dumping platform or tilting trackection may assume various forms, but the nechanism illustrated in detail in Figs. 9, 0 and 11 has been designed with special regard for use in connection with the improved car-dumping and transferring mechanism hereinbefore described.

teferring to the figures just named, as also to Figs. 1 and a, two sets of stops 40, 4:0 and ll, 4-.1, will be seen to be provided, said stops being oscillatory in a vertical plane transverse to the line of movement of the car To this end they are mounted upon short shafts or spindles L2 and 43 just outsi e the rails of the track so that, when swung outwardly as shown in Fig. 11, car may pass freely along said track, whereas when said stops are tilted inwardly as in Fig. 10, the upper horn-like ends of the stops will lie over the rails and engage the wheels of the car, thus stopping the same.

Oscillation of the stops is secured through two double levers 44 and 4-5 in a roclnshaft 4-6 disposed beneath the track, the opposite arms of the respective levers being conn cted by means of suitable links i? with the lower ends of the corresponding stops. A weighted arm L8 on said rock shaft is adapted to normally retain the stops in the position illustrated in said two figures, in which the rear pair of steps 4-1, d1 leave the track open, while the forward pair 40, 4-0 is oper ative. The link connections l? from the stops to the actuating double lever arms 4rd and d5 below the track are reversely disposed in the case of the two pairs, so that when said rear pair is swung inwardly the forward pair will be thrown out. This actuation of the double lever arms is achronized with the movement of the tilting or floating track-section i, a bell-crank lever 49 being disposed with its one arm in position to be engaged by the lever member 11 when in its lower horizontal position, which corresponds with the lower position of said track-section, wherein registers with the lower track 1. The rocking motion of said bell crank, produced by the engagement of the lever member with its one arm, is communicated to the shaft 46 carrying the double levers fl and l5 by means of a con necting rod 50 and horizontally disposed bell-crank 51 that is in turn connected with an upstanding lever 52 on the shaft intermediate between the two double lever arms.

The operation of the stop mechanism will readily appear from what has just been said. Thus it will be seen that the lower posi tion of the track-section the forward horns are thrown outwardly, thus leaving the car, which has been held thereby, free to proceed along the track onto the traclnsection at. The latter being thereupon raised to dump and transfer such car said forward pair of stops swings back into position under the influence of the weighted arm 48 and the rear pair of horns which had restrained the following car, is thrown out so that such car can advance until it is stopped by the forward pair of horns. This operation will obviously be repeated as often as the tracksection is restored to its lower position in which it is adapted to receive a fresh car from the lower track.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the fol.- lowing claims or the equivalent of such stated means be employed.
